This invention relates to garment presses of the type including a frame whereon is mounted a relatively fixed lower buck and whereon is fulcrumed a lever carrying an .5 upper buck arranged, when the lever is rocked, to perform swinging movement to wards and away from the lower buck, a cylinder connected through the intermediary of appropriate valves to a source of pressure 10 fluid supply, and a piston operatively con nected to the lever and reciprocable in the cylinder under the influence of pressure fluid so as to cause the lever to perform the requisite rocking movements.

In garment presses of this type as C011- structed heretofore it has been customary to form the cylinder as a unit separate from the frame supporting the lower buck and to mount the cylinder on the frame so as to perform oscillatory movements relatively to the frame.

The present invention provides an improved garment press of the typedescribed and is characterized broadly by the feature 25 that the pressure fluid cylinder, the frame which carries the lower buck and the fulcrum for the lever which carries the upper buck are constituted as a self-contained unit.

A garment press constructed in accordance with the invention is illustrated in the figure of the drawing which is a part side elevation part section.

The garment press shown includes a frame 1 whereon is mounted a lower buck 2 and whereon is fulcrumed at 3 a lever 4 carrying an upper buck 5. The buck 5 is arranged, when the lever 4 is rocked, to perform swinging movement towards and away from the lower buck 2. A cylinder 6 is connected through the intermediary of appropriate valves to a source of pressure fluid supply, and a piston 7 is operatively connected to the lever and reciprocable in the cylinder 6 under the influence of pressure fluid so as to cause the lever 4 to perform the requisite rocking movements.

The pressure fluid cylinder 6, the frame 1 and the fulcrum 3 for the lever are constituted as a self-contained unit.

The lever at is a lever of the first order and is rocked about its fulcrum 8 through the intermediary of a toggle of which thelinks 8, 9 are interposed between the efiort end of the lever at 10 and a fixed part at 11 of the self-contained unit incorporating the cylinder 6. The pivot pin 12 connecting the linlrs 8, 9 is formed as a follower to a scroll cam 13 which is connected to the piston 7 by a connecting rod 14 and is mounted for oscillathe the limb 16 is so positioned that the follower enters the limbs 16 when the links 8, 9 of the toggle are closely approaching straight ened position. v r v It will be seen that the configuration of the cam is such that, in the first forward movement of the piston 7, there is imparted to the upper buck 5 a rapid downward movement and, in the continued movement of the piston 7, there is imparted to the upper buck a less rapid movement so that the pressure 7 tending tobring the bucks o and 2 together is at its maximumwhen the upper buck enters into contact with the garment to be pressed. I i

The lever incorporating the cam is formed as a pointer at 17 adapted to register with a graduated dial 18 indicating the pressure to which the garments are exposed.

I claim l. A garment press ofthe type described comprising a frame, a lower buck supported by said frame, a lever of the first order movable about a fulcrum on said frame, a toggle interposed between said frame and said lever and including-two links united by a pivot pin, a scroll cam mounted on said frame to swing about an axis coinciding with the fulcrum of said lever and cooperating with said pin'so that said pin acts as a follower to said cam and so that, in the movement'of the cam, said toggle is caused to bend and. to

straighten, an upper buck carried by and participating in the movementsrof said lever, a pressure fluid cylinder, a piston reciprocable in said cylinder under the influence of pressure fluid admitted to and exhausted from said cylinder, and a connecting rod operatively connecting said piston with said cam, said fulcrum and said cylinder being formed as a self-contained unit.

2. A garment press of the type described comprising a frame, a lower buck supported by said frame, a lever of the first order movable about a fulcrum on said frame, a toggle interposed between said frame and said lever and including two links united by a pivot pin, a scroll cam mounted on said frame to swing about an axis coinciding with the fulcrum of said lever and cooperating with said pin so that said pin acts as a follower to said cam and so that, in the movement of the cam, said toggle is caused to bend and to straighten an upper buck carried by and participating in the movements of said lever, a pressure fluid cylinder, a piston reciprocable in said cylinder under the influence of pressure fluid admitted to and exhausted from said cylinder, and a connecting rod operatively connecting said piston with said cam, the configuration of said cam being such that, in the first forward movement of said piston, there is imparted to said upper buck a rapid downward movement and, in the continued movement of said piston, there is im parted to said upper buck a less rapid movement so that the pressure tending to bring said bucks together is at its maximum when said upper buck enters into contact with a garment to be pressed between said bucks, said fulcrum and said cylinder being formed as a self-contained unit.

3. A garment press of the type described comprising a frame, a lower buck supported by said frame, a lever of the first order movable about a fulcrum on said frame, a toggle interposed between said frame and said lever and including two links united by a pivot pin, a scroll cam mounted on said frame to swing about an axis coinciding with the fulcrum of said lever and cooperating with said pin so that said pin acts as a follower to said cam and so that, in the movement of the cam, said toggle is caused to bend and to straighten, an upper buck carried by and participating in the movements of said lever, a pressure fluid cylinder, and a piston reciprocable in said cylinder under the influence of pressure fluid admitted to and exhausted from said cylinder and a connecting rod operatively connecting said piston with said cam, said cam formed as an L-shaped groove one limb of which accommodates said pivot pin follower when said upper buck is subject to rapid movement and the other limb of which accommodates said pivot pin a when said upper buck is subject to less rapid movement and the unction of said first limb and said second limb being so positioned that said pivot pin enters said second limb when said links of said toggle are closely approaching straightened position.

In testimony whereof I have signed my name to this specification.
